WILLIAM WILKINS, OF BRIDGEPORT, CONNECTICUT.

HOSE-NOZZLE.

SPECIFICATION forming part of Letters Patent No. 370.836, dated October 4, 1887.

Application filed March 5, 1887.

To all whom it may concern.'

Be it known that I, WILLIAM WILKINs, a citizen of the United States, residing at Bridgeport, in the county of Fairield and State of Connecticut, have invented certain new and useful Improvements in Hose-Nozzles; and I do declare the following to be a full, clear, andy exact description of the invention, such as will enable others skilledinthe art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

My invention relates to hose-nozzles,and to that class of nozzles which may be made at pleasure to throw a solid stream or a shower of spray; and the invention consists in the novel construction, as more particularly specied.

To more fully understand my invention, reference is had tothe drawings, and to gures and letters of reference marked thereon.

Figure 1 represents a side elevation of the nozzle complete. Fig. 2 represents a front View of same. Fig. 3 represents a longitudinal section of Fig. I. Fig. 4 represents a front elevation of the nozzle with end plug and waterkey removed. Figs. 5, 6, 7, 8, 9, l0, Il, and 12 represent detail views.

Its construction and operation are as follows:

A represents the body of the nozzle; B, the water-key; C, end plug to produce the spray or solid stream; D, end of nozzle, having taper mouth E to receive plug C.

In Fig. 6 is seen a sectional view of the nozzle through dotted line :vof Fig. l,showing the end D with taper mouth E, the key B and plug C being removed. At the bottom of the taper mouth E is the projection or shoulder a, having threaded interior b. Said projection is surrounded by the annular space or chamber c, leaving the partition cZ between space c and the taper chamber e. Through partition cZ are the holes c', (see also Fig. 4,) opening a communication between chambers c and e. The taper sides f of plug C correspond approximately to the taper of mouth E, the threaded end g engaging with the threaded projection a of the nozzle, the end or shoulder h of plug C abutting rmly against proj ec- Serial No. M9382. (No model.)

tion a, (see Fig. 3;) but the taper sides or surfaces of plug C and mouth E are not brought in close contact, but by means of the shoulder h of said plug the narrow space is left between said surfaces. The manner of attaoh ing the plug C to the nozzle may be somewhat varied, but stillembrace the same principles as above described. For instance, in Fig. 11 projection a is removed and partition d is made thicker and threaded to receive threaded end g of plug' C. The shank i" of said plug (see Fig. 12) is sufficiently reduced in size so as to leave chamber c substantially as shown in Figs. 3, 4, and 6.

Through the plug C is the channel j, communicating with chamber e for the solid stream. I prefer to make the taper key B, which fits the chamber e, hollow, or, in other words, with the interior chamber, Z. Through one side ot' key B, and-opening into chamber Z, is the hole k, (see Figs. 3 and 9,) whose diameter is equal to the diameter of channel j of plug C. On the reverse side of the key B (see Fig. l0) are the holes m, opening also into chamber Z, and corresponding as to position with holesa of the nozzle. tional View of the front portion of the nozzle through dotted line x of Fig. l. When the key B is turned in the position as shown at Fig. 3, the holes m of the key and holes u. of the nozzle will coincide, thus opening a direct communication between chambers c and Z. Through the rear portion, n, of the nozzle is the water-way o, (see also Fig. 8, which represents a sectional view through dotted line :v of Fig. 1,) whose diameter is equal at least to the space covered by the four holes m of key B. The incoming water, as indicated by the arrows, (see Fig. 3,) will pass through hole la to chamber Z, thence through holes m and a to chamber c, and out through space or aperfl ture Z, in the form of spray, in greater or less volume, according to the width of said openlng t. tween holes m will close the channel j, thus directing the full force of the water through holes m and a', as described. Reversing the position of key B will bring holes m of the key in communication with waterway o and hole k with channel j. The incoming water, entering through holes m, will pass out through The central space, p, (see Fig. 10,) be` (See Figs. 4 and 7.) Fig. 7 is a sechole 7c and channel j, issuing from the end of plug C in a solid stream, as seen at Fig. l. To shut off the water the key B is given a quartertnrn, as shown in Fig. 2, the solid portion of said key closing holes a and o. The number of holes in the nozzle, as represented by a', may be increased or decreased, as required. All that is necessary is to keep the space i filled and sufficient pressure to produce the spray. In constructing the nozzle, the Width of space t being determined, the plug C is screwed suiiiciently firm against its seat in the nozzle so as to prevent its becon1 ing accidentally loosened. Should the apertnre or space t' and holes a become filled with sediment, the plug C can be readily removed and the nozzle cleaned.

Among the advantages of the nozzle above described over others of its class are its simplicity, cheapness of manufacture, and readiness with which it can be taken apart and cleaned.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

In a hose-nozzle, the combination, with noz zle A, having taper mouth E, chamber c, and holes a', connecting chambers c and e, of plug C, having threaded end g to engage with the threaded portion of the nozzle, said plug having taper sidesf, corresponding approximately to the taper of mouth E of the nozzle, and Water-channel j through said plug and communicating with chamber c, plug C so arranged in relation to the mouth E that aperture i is formed for the passage of water in the form of spray.

In testimony whereof I affix my signature in presence of two Witnesses.
